The molecular building blocks that make up DNA absorb ultraviolet light so strongly that sunlight should deactivate them – yet it does not. Now scientists have made detailed observations of a "relaxation ...

A set of experiments conducted on the Nike krypton fluoride (KrF) laser at the U.S. Naval Research Laboratory (NRL) nearly five years ago has, at long last, earned the coveted Guinness World Records title for achieving "Highest ...

A new, extremely thin kind of light detectors was created at Vienna University of Technology. Two very different technologies were combined for the first time: metamaterials and quantum cascade structures.

Imaging and mapping of electric fields at radio frequencies (RF) currently requires the use of metallic structures such as dipoles, probes and reference antennas. To make such measurements efficiently, the ...

A revolutionary new £1M laser instrument in the UK is set to illuminate the innermost workings of DNA, protein, enzyme and other molecules that play a critical role in key natural processes in humans, animals ...

Physicists are continuously advancing the control they can exert over matter. A German-Spanish team working with researchers from the Max Planck Institute for Nuclear Physics in Heidelberg has now become ...

Bathymetric lidars – devices that employ powerful lasers to scan beneath the water's surface – are used today primarily to map coastal waters. At nearly 600 pounds, the systems are large and heavy, and ...

Human biology is a massive collection of chemical reactions, from the intricate signaling network that powers our brain activity to the body's immune response to viruses and the way our eyes adjust to sunlight. ...

A research team led by physicists at the University of Wisconsin-Milwaukee (UWM) has proven a method that makes it possible to find the atomic structure of proteins in action by producing "snapshots" of them ...

A team of researchers from the University of California, San Diego have demonstrated a way to emit and control quantum light generated using a chip made from silicon—one of the most widely used materials ...

By solving a six-dimensional equation that had previously stymied researchers, University of Nebraska-Lincoln physicists have pinpointed the characteristics of a laser pulse that yields electron behavior ...

An international team, including scientists from DESY, has caught a light sensitive biomolecule at work with an X-ray laser. The study proves that X-ray lasers can capture the fast dynamics of biomolecules in ultra slow-motion, ...

Scientists at the Department of Energy's SLAC National Accelerator Laboratory are combining the speed and precision of robots with one of the brightest X-ray lasers on the planet for pioneering studies of ...
